Hi @KavitaaG,

Welcome to the HP Support Community.

Thank you for posting your query. I will be glad to help you.

A non-working fan on your HP Spectre x360 14 can lead to overheating and system errors (often "Fan Error 90B"). To quickly fix this, perform a hard reset, clean the vents to remove dust, update your BIOS using the HP Support Assistant, or check your fan cables.
 

Step-by-Step Troubleshooting:
 

1. Perform a Hard Reset:

Sometimes a fan fails to turn on due to residual static charge in the laptop's memory. 
 

• Shut down your laptop and unplug the power adapter.
   
• Disconnect all USB drives and external devices.
   
• Press and hold the Power button for about 15 seconds.
   
• Reconnect the power and turn the laptop on to see if the fan starts spinning.

2. Clean the Vents and Fans:

Dust buildup is a frequent cause of fan failure.
 

• Turn off the computer and use a can of compressed air to blow through the vents and along the fan opening.
   
• If you are comfortable opening the case, you can remove the bottom panel to clear any blockages on the blades directly.

3. Update Your BIOS and Drivers:

Outdated firmware can cause your system's thermal management to malfunction. 
 

• Run the HP Support Assistant on your Windows system to find and install the latest BIOS and system updates.

I hope this will help.

 

Take care and have a good day.
